So to continue the armchair diagnosis, ha ha. The pics of the palm-bumps remind me of some similar-looking things my mother has.
The doc identified them as telangiectasias. My mother has what used to be called CREST Syndrome, which is an acronym for Calcinosis, Raynaud's, Esophageal Dysmotility, Scleroderma, and Telangiectasias. It's pretty much diagnosed by whether you have multiple of these problems, and she had the R, E, and T at least. The term "CREST Syndrome" is now not favored - it's now called a "limited cutaneous form of systemic sclerosis", because that has a much better ring to it.
At any rate, my mother has the T on her face mostly. The description of the T on the wikipedia page for CREST Syndrome fits your description well. But then T is actually the medical term for "spider veins", and the images of those are not at all helpful for hands. So who knows if that's what you have. I don't think they usually feel raised like bumps, though.
So I can see why the doc might be most worried about the palm-bumps. Those seem like the oddest symptom and possibly may be indicating something deeper and more systemic. All of those sorts of systemic and auto-immune issues are really tricky to diagnose and unfortunately most don't have good treatments, so figuring them out early is key.
And, sheesh...after I wrote all that, I realized I had consistently written about my mom in the past tense for some reason. I had to go change it, because she's still very much alive, active, and healthy 70-yo.

Don't tell her I did that.
